Rant of sort, advice needed

Hi, so first post ever, but I'm feeling really icky right now and I just want to talk.

I like this guy, but he lives on the east coast. For reference I'm from the west, so it's quite a distance. We like each other, and are dating, kinda, it's complicated. We agreed that we want to keep in touch and try to meet up one day. Unfortunately, I feel that it's unlikely that we will ever meet and that makes me really sad. He's genuinely improved my life, and I've been doing a lot better with mental health and life in general since I've started talking to him.

For anyone out there who's in a ldr, how do you cope with the loneliness? I guess I'm just looking for reassurance that it's worth it? Any examples of ldr that have worked out would be amazing.
